Referring to the drawings, and to the embodiment of the invention which is illustrated therein, and having referenceat first to Fig. 7 1, there is shown a file comprising a series of sheets 15, eachof which in the present example is folded as at 16 (see Fig. 3) In the present example,the sheets are of comparatively light weight stock, and two identical sheets are nested together,that is to say, onefolded sheet is received within the fold of another identical sheet. In Fig. 3, one of these sheets is turned back at one corner to expose the .50. underlying sheet. One or more sheets of this into proper registration therewith.

kind,-as desired, may be supported on each I:

of the sheet carriers now to be described.

Each sheet, or group of sheets, is carried a by an elongated sheet carrier, hereina. flat, resilient, metallic bar 17, with which the ,55 sheet has interlocking engagement; in other f words, the sheet and. the: carrier haveinter- I locking means normally preventing. separation of one from the other by bodily movement. In the present example, such in. terlocking means. (see Fig; 4) are in the form of one ormore pairs of oppositely directed locking projections 18 on the carrier, and complementalopenings 19 in the sheet. Each projection comprises, a body 20 and a tongue 21, the latter extending lengthwise of the carrier, and the outer ends of the tongues of each pair of projections preferably extending toward each other. In this instance, the projections are formed on one of the longitudinal edges of the carrier. Normally the openings 19 are elongated lengthwise. of the carrier, and they are of sufficient length to permit the projections 18 to be withdrawn therefrom when the projections arebrought ,75

The tongues 21 extend beyond the respective openings in which the projections are received, and overlie'the sheet, therebyloeking the sheet to the. carrier. The lengthsv of 80 the openings19 and their relative arrange- 'ment are such that, by proper manipulation of the sheet and the carrier, the openings can be brought intoregistration with the projections, and the latter then removed from the former; I I i This operation is illustrated in itsfirst step by Fig. 5, which shows thesheet: as it appears after a portion of, it has been moved lengthwise of the carrier, to bring one of the openings 19 into proper registration with one of the projections 18-, to permit that portion of the sheet then 'to be moved transverselyof the carrier, to disengage that part of the sheet from the carrier. During this operation, of

course, the projection will'pass through the bring the other opening, 19 into. registration."

with the other projection 18, whereupon the latter may be caused to pass through the former in a direction transversely of the carrier, thereby to separate the sheet and the carrier.

The foregoing description is of the carrier and the sheet in their simplest form, but 7 when desired for purposes which will presently appear, there may be, and there are 10 herein, provided additional carrier projections and sheet openings. One purpose which will be served by the employment of these is the offsetting of the sheets length wise of their respective carriers, so that by offsetting one or more sheets with relation to the remainder, by their offset position they are distinguished. Another purpose to be served by additional projections is the attachment thereto of auxiliary sheet carriers,

2 whichf'carry auxiliary sheets.

In the embodiment shown, the carrier is provided with additional projections which, for convenience, will be designated 18 18 and 18, and their characteristics are similar '25 to those of the projectons 18. The sheet is provided with additional openings which, for convenience, are designated 19 19 and 19.

Referring now to Fig. 2, the right-hand projection 18 and the projection 18 aiford pivotal support for auxiliary sheet carriers 22, which carry an auxiliary sheet 23, herein of relatively thicker stock than the sheets 15. Each of these auxiliary sheet carriers is, in effect, a hinge piece which, as shown in Fig. 9, has two arms 2a and 2 1, between which the sheet is received, the arm 24' being provided with one or more, herein a pair of lugs 25, received in perforations 26 provided in the sheet. The sheet is conveniently removed with its hinge pieces from 4 withdrawn from the secondpivot.

This auxiliary sheet may be offset from the position shown in Fig. 2 by shifting it to the right and attaching it to the projections 18 and 18*. Similarly one or more of the sheets 5 15 maybe oifset by first removing them from their carrier, then shifting them to the right,

and finally re-attaching them to the carrier so that, reading'froi'n left to right in 6 for example, openings 19. 19, 19 and 19 respectively receive and lock with projections'18 18, 18 and 18 It should be understood, of course, that before this shifting can beaccomplished, the auxiliary sheet 23 must first be dismounted, and after the shifting oohas'taken place, the auxiliary sheet can be restored to the main carrier, and it can be placed in either of the two described po sitions on the carrier. Thus it is apparent that the sheets and the carriers are susceptible of -a considerable variation in relative arrangements, by the simple provision of a sufficient number of projections on the carrier and corresponding openings in the sheet. Also, it is to be remembered that there may be more than one of the sheets 15 on each carrier, and that accordingly, one of these may be oifset with relation to the other on its carrier.

Each of the sheet carriers 17 has reduced terminal portions 27, received in sockets (see Figs. 7 and 8), there being a series of pairs of these sockets supported by an appropriate support, herein a plate of sheet metal bent to form a back 28. two side walls 29 and two front flanges 30, forming a pair of channels 31, in which the sockets are received. In the present example, each socket has spring means, herein a tongue 32, pressing against the inner surface of the front flange 30, and resisting movement of the socket in the channel. Herein, the socket is conveniently made of a piece of sheet metal bent to provide four walls, one of which is the spring tongue 32, another a side wall 33, another a back wall 34, and another a wall 35, which is provided with an aperture 36, in which the terminal portion 27 of the sheet carrier is received. Theshape anddimensions of the aperture and of the end of the carrier are such that the latter is capable of turning movementwith relation to the socket. The width of the aperture 36 (i. e., lengthwise of the channels) is only slightly greater than the width of the terminal portion 27, as a result of which accurate spacing of the overlapping margins of the sheet is maintained. The other dimension of the aperture is such that free turning movement of the carrier, as well as in-and-out movement relatively to theback of the frame. are permitted. As a result, the sheets will normally lie fiat in place, but may be turned from a depending position to an upstanding position, that is to say, through an angle of substantially 180 degrees.

In this embodiment, the flange 30 slopes inwardly toward the back wall 28 of the frame, and the wall 35 projects outwardly beyond the free edge of the flange, but not beyond that part of the flange which adjoins the side wall 29. Thus, while the extremity of the wall 35 is rendered accessible for crigagement by the finger, to withdraw the socket from the channel, yet the extremity of the wall does not present an obstruction, and does not increase the front-to-back thickness ofthe file. Herein, the shape and relationship of the spring tongue 32 to the flange 30 are such that the tongue yields'and springs rearwardly when suflic-ient force is applied to the projecting portion of the wall '35 to force the socket out of the channel,

the spring tongue yielding rearwardly as it passes behind the edge of the flange.

As already intimated, the cards 23 may be with two openings which receive sa1d pro ections' and are elongatedlengthwise oi said "me d-# omitted if desired. On the other hand, when the cards 23: are used", the folded sheets 15 may be omitted. When both: sets are used, the full capacity of the file is obtained. Herein,the sheets 15 are provided with apertures 37 (see Fig. 3)',along the line of the fold I6, to give them greater flexibility at this point.
